Limited Slip Differentials - Positraction Units

A limited slip differential, also known as a positraction unit or posi, allows for automatic traction control when navigating difficult road surfaces or weather conditions. In a standard open differential power moves freely to the wheel with the least resistance. In a limited slip differential when a wheel begins to slip the unit applies friction resistance to limit excessive power travelling through a single wheel, ensuring both wheels rotate with even power.

Many trucks and muscle cars come standard with a factory limited slip, however, these can wear out or even break over time. At DiffsOnly we carry a variety of limited slip differential units for a wide range of rear wheel drive and 4×4 vehicles.
